Abstract:
A capacitor input circuit for a mobile power supply includes a bulk capacitor and a switch. The switch connects the bulk capacitor to receive a rectified AC voltage from a rectifier when an AC line voltage input to the mobile power supply is lower than a threshold voltage. When the AC line voltage is greater than the threshold voltage, the switch electrically floats the bulk capacitor.
